Book Description
Dans un contexte de préoccupation accrue d'économie d'énergie, l'intérêt que présente le développement de stratégies visant à minimiser la consommation d'un bâtiment n'est plus à démontrer. Que ces stratégies consistent à recommander l'isolation des parois, à améliorer la gestion du chauffage ou à préconiser certains comportements de l'usager, une démarche préalable d'identification du comportement thermique de bâtiment s'avère inévitable. Contrairement aux études existantes, la démarche menée ici ne nécessite pas d'instrumentation du bâtiment. De même, nous considérons des bâtiments en occupation normale, en présence de régulateur de chauffage : inconnue supplémentaire du problème. Ainsi, nous identifions un système global du bâtiment muni de son régulateur à partir de : données de la station Météo France la plus proche ; la température de consigne reconstruite par connaissance sectorielle ; la consommation de chauffage obtenue par système de Gestion Technique du Bâtiment ou par compteur intelligent ; autres apports calorifiques (éclairage, présence de personnes...) estimés par connaissance sectorielle et thermique. L'identification est d'abord faite par estimation des paramètres (7) définissant le modèle global, en minimisant l'erreur de prédiction à un pas. Ensuite nous avons adopté une démarche d'inversion bayésienne, dont le résultat est une simulation des distributions a posteriori des paramètres et de la température intérieure du bâtiment. L'analyse des simulations stochastiques obtenues vise à étudier l'apport de connaissances supplémentaires du problème (valeurs typiques des paramètres) et à démontrer les limites des hypothèses de modélisation dans certains cas.

Book Description
Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Book Description
Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Book Description
This volume contains 44 papers and 2 abstracts from a international conference on African small ruminants research and development. eleven papers and 1 abstract deal with the importance of small ruminant production systems and economics. Another 11 describe and analyse feed resources and feeding systems and there are 6 papers on reproductive problems and their solutions. Seven papers and 1 abstract review the prevalent health problems under various management systems and present the solutions to these production constraints. The last 9 papers deal with breeds, breeding systems and breed improvement.

Book Description
Taking authentic texts from a variety of sources - the human body on CD-ROM, a fish recipe, 'L'Etranger' and many others - this book uses them as a starting point for the illustration and explanation of key areas of French grammar. It includes a range of exercises, many of them text-based.

Book Description
It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

Book Description
Establishes Geotechnical Reliability as Fundamentally Distinct from Structural Reliability Reliability-based design is relatively well established in structural design. Its use is less mature in geotechnical design, but there is a steady progression towards reliability-based design as seen in the inclusion of a new Annex D on "Reliability of Geotechnical Structures" in the third edition of ISO 2394. Reliability-based design can be viewed as a simplified form of risk-based design where different consequences of failure are implicitly covered by the adoption of different target reliability indices. Explicit risk management methodologies are required for large geotechnical systems where soil and loading conditions are too varied to be conveniently slotted into a few reliability classes (typically three) and an associated simple discrete tier of target reliability indices. Provides Realistic Practical Guidance Risk and Reliability in Geotechnical Engineering makes these reliability and risk methodologies more accessible to practitioners and researchers by presenting soil statistics which are necessary inputs, by explaining how calculations can be carried out using simple tools, and by presenting illustrative or actual examples showcasing the benefits and limitations of these methodologies. With contributions from a broad international group of authors, this text: Presents probabilistic models suited for soil parameters Provides easy-to-use Excel-based methods for reliability analysis Connects reliability analysis to design codes (including LRFD and Eurocode 7) Maximizes value of information using Bayesian updating Contains efficient reliability analysis methods Accessible To a Wide Audience Risk and Reliability in Geotechnical Engineering presents all the "need-to-know" information for a non-specialist to calculate and interpret the reliability index and risk of geotechnical structures in a realistic and robust way. It suits engineers, researchers, and students who are interested in the practical outcomes of reliability and risk analyses without going into the intricacies of the underlying mathematical theories.
